Linked list confusion :/ !!!

I am having a couple of problems understanding linked lists and the ListIterator

LinkedList<String> list=new LinkedList<String>();
ListIterator<String>iterator=list.listIterator(); // What does this dot notation point too??

Is .listIterator simply a method which takes all the objects/elements in the list and passes them to the Iterator interface which can then cycle through them using its methods or is there something else happening ?? :/
